M ECHANICAL POWER.

SPECIFICATION forming part of Letters Patent No. 543,392, dated July 23, 1895.

Application filed April 27, 1 8 95 i lowing is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to certain improvements in power-motors.

The object of the invention is to provide an improved construction of oscillating or swingin g weight-motor for multiplying power, and which is particularly adapted to be interposed between the prime motor and the machine or devices to be driven, and which will be kept in motion bythe prime motor and will increase the power thereof and apply it to the .machine to be driven.

The invention consists in certain novel features of construction and in combinations and arrangements of parts more fully and particularly described hereinafter, and pointed out in the claim.

Referring to the accompanying drawings, Figure 1 is a side elevation of the improved machine. upper weight of the pendulum removed.

In the drawings, a indicates a supportingframe comprising main side bars and uprights, which is most rigidly and strongly constructed and preferably mounted onsupporting-Wheels b, and provided with a tongue 0, so that the machine can be easily transported.

d is astrongly-constructed swinging pendulum comprising an upright pivoted or fulerumed at e between its ends and the top bars of the frame. The greater portion of the length of the pendulum is preferably arranged beneath its fulcrum, and at its lower end is provided with the weight f, here shown as a receptacle containing rock or any suitable weight. The upper end of the pendulum is also provided with the heavy weight g, here shown in the form of a receptacle containing stone or other material. Arms h extend out through opposite sides of the pendulum at or Fig. 2 is a top plan view with the Serial No. 547,331. (No model.)

about its fulcrum-point and are provided with weights j represents springs connected with opposite sides of the upper end of the pendulum and secured t6 opposite ends of the frame, having a tendency to maintain the pendulum in its normal upright position, so that as the pendulum swings these springs will alternately distend and compress.

j" is a drive-shaft mounted in the frame and having pulleyj' driven from the prime motor, such as an engine or horse-power, (not shown,) by beltj This shaft j" has a crank j connected by link It to the rigid arm is from the lower end of the pendulum, so that the rotation of shaftj" will rock pendulum and maintain the same oscillating at the uniform stroke.

Z is a pitman eccentrically pivoted to pulleyj', and at its opposite end eccentrically pivoted to pulley m, rigid on the shaft m, journaled in the opposite side of the machine and having the crank m loosely connected by pitmen m with the pendulum below the fulcrum thereof. This shaft m has a pulley m driving shaft 72. through the medium of belt n and pulley 01 The shaft 01 has pulleys n and a which can be connected with the machine or other devices to be driven by means of belt 0, or any other suitable powertransmitting means.

It should be observed that two crank-shafts m andj" are coupled together to rotate in unison by the pitmen Z, and that the prime power coupled to these shafts is connected with the pendulum and keeps the pendulum oscillating back and forth-at a uniform stroke and carries the same beyond the dead-centers, so that said power is only necessary to start the pendulum and keep it going and that through the medium of this pendulumthe initial power is multiplied and transmitted to the machine or other devices to be driven.

. It is evident that various changes might be made in the forms, arrangements, and constructions of the parts described without departing from, the spirit and scope of myinvention. HenceI do not wish to limit myself rco to the exact construction herein set forth, but consider myself entitled to all such changes as fall within the spirit and scope of my invention.

Having thus fully described my invention, connected with the same end of the pendulum what I claim as new, and desire to secure by and the pitman eccentrically connecting said Letters Patent of the United States, istwo shafts.

A frame, a pendulum fulcrumed therein In testimony that I claim the foregoing as 15 -5 between its ends and having the weights at my own I affix my signature in presence of both ends and on opposite sides thereof and two witnesses. the 0 ositel acting s rin s, a shaft con- 7 a J r 1 i necte with the prime r otoi and having a CHARLES MA FrlHEVS' crank connected to one end of the pendulum, I Vitncsses:
